If it was me, I would have a pro weld a bolt on there and try backing it out with a box end wrench (6 point). Use a bernzall torch with propane to heat up the housing (not too much heat or it will expand the bolt and defeat the purpose). Then back it out.
After it is out, I would figure out what size the stock bolts are and get a helicoil for it. Helicoils are simple to use, and very strong. I have used them plenty and they are a mechanic's second best friend (vise grips will always be number one in my books, BFH takes number 3, 5 foot breaker bar is #4).
Like Heather mentioned, run a drill bit the size of the diff cover bolts through the rock ring to get rid of all that powder coat. It is amazing how much that stuff screws up alignment. I had the same problem while installing my lift (Rusty's Spacer, too much powder coat for the studs to fit through the spacer).
Well, it's been along weekend. I've been turned away by 4 "pro" welding shops. I finally went down to Gasoline Alley today near the Indy 500 race track and started talking with race teams. I was referred to a driveline specalist. It's finally out. Turns out I went back into my garage and brought the remaining bits out and noticed they were the titanium bits, so it was a titanuim one broken in the bolt. And it was already at 75% the diameter of the broken bolt, so no room for another bit next to it.
The shop today used high pressure water/fluid drills, drilling, and good old mining one little bit at a time, and got it out - first the bit, then the bolt. Then rethreaded the bolt hole.
All other methods were tried, but this was the last chance.
$291.35 (at least I got the 75W140 synthetic lube)
Ironically, the replacement Rock Ring was on my front door when I got home. Now, I've got about $450 in this cluster **** with nothing to show for it.
DO NOT ORDER A POISON SPYDER ROCK RING IF YOU ARE EXPECTING A PRECISION PRODUCT.
Anyhow, thanks to EVERYONE for all the help. I'm just glad this is over for now. The Rock Ring will make a good paper weight.
